This invention relates to a new and useful device in the nature of a back rest particularly adapted for use in Acormection with motor vehicles for the purposeroii providing a comfortable support lor the backs of passengers riding in motor 'vehicles equipped with my improved device, so as not to fatigue the passengers. f

The object ett the invention is to provide a baci; rest et novel eonstr ction and arrangement et parts, hereinaitter more fully described, claimed and illustrated in the accompanying drawing.

Fig. 1 shows a side elevational view of a motor vehicle equipped with my improved baclr rest constructed in accordance with my invention.

Fig. 2 a 'front elevational view of my improved back rest.

Fig. 3 is a longitudinal sectional view oit my improved device, taken on the line 3 3 et Figure 2.

l? i is a transverse sectional view taken on the line ffl of Figure 2.

Fig. 5 is a perspective view illustrating a modii'ieation oi? my in'iproved baclr rest.

fis here embodied, my improved baclr rest comprises a supporting member, of rectangular shaped construction, consisting o" side loi'igitudinal members 10 and 11, attached to theiinain member 12. Y rilhe side members and 1l, extend below the main member 12, and have attached thereto, at their extended portions, cross members 13 and 141-.

ifhe guide members and 1G, are attached to the main member 12, in proximity to the ce2 ter portion thereof, and are extended lon: gitudinally thereto. The guide members 15 and 16, are provided with longitudinal grooves 17 and 13, respectively, adapted to receive the longitudinal projecting elements i9 and 20, oi' the'engaging member 21, attached to the baclr rest proper The engaging member 21, is longitudinally positioned relative to the bacs rest proper 22, at or near the center portion thereof.

rllie rollers 23 and 24, are rotatively mounted on a pin, carried in extended elements ot the bracket 26, attached to the main member 12. lt being understood that a plurality oi the latter described rollers are provided, as a means ot slidably mounting the beck rest proper 22, on the above described supporti member. lt being further understood that the bnclr rest proper 22 will ber held or maintained in a tired position, hori- 1927. Serial Nb. 208,671.

Zontally relative to the supporting member, by means of the engaging member 21, as above describedand vset torth.

rlhe springs 27, are attached to the upper portion et the main member 12, and to the bacl; rest proper 22. Similar springs 28 are attached to the back rest proper 22 and to the lower portion ot the main member 12. The tirst mentioned springs`27 being somewhat stronger than the. springs 28. The latter described construction being such as will'permit the springs 27 and 28 to normally hold the back rest proper slightly above the said .supporting member, so as to permit the lower portion et the supporting member to normally extend below the lower portion ot the back rest proper.-

The'upper side of the back rest proper 22, may be covered with any suitable material 29, such as leather, imitation leather, or similar fabric, stulled withhair 30, moss, or the like. A flexible member 31, preferably of similar material as the covering material 29, is attached to the upper portions of the back rest proper 22, and the main member 12. The said 'flexible member 31 being provided with a certain amount of looseness or slackness, so as to permit of the liereinbefore described movement ot the back rest proper 22, as a means of limiting the movement o1 the back rest proper 22.

ln Figure 1 o1 the accompanying drawing, l have shown my improved back rest, designated by the reference numeral 32, in position over a back cushion 33 of a motor vehicle rear seat, sov as to be removed when desired. have also shown my improved back rest, designated by the reference numeral 3ft, in position on a back trame ot the front seat of the said motor vehicle, as same would appear when constructed as an integral part of the front seat, -in which event the above mentioned supporting member is rigidly attached, by screws, bolts, or the like, to the above mentioned back frame of the front seat.

In Figure 5 oit the accompanying drawing, 'l have shown the above mentioned guide member 15, pivotally attached at one eXtremity, as at 36', by a pin, to the upper portion of the main member 12. The plate member 37, isA

attached to the free extremity of the guide member 15, and has formed therein an elongated circumferential aperture 38, adapted to receive the threaded member 39, as a means of adj ustably attaching the guide member 15 to the main member 12. The above described construction being such as will permit the guide member l5 to adjustably engage the engaging member 2l, so as to hold the engaging member 2l in various fixed positions. It should be noticed that when the guide mem ber l5 is parallel with the member 16, the slide may merely move therebetween. dition of the device the guide members act as true guiding members. The guide member I5 may be an gul-arly positioned and thus clamped by the screw 39 for binding the slide 21 in any desired position. rIhus the seat back may be free between the guides or may be iXed at any desired height. The plate member 110, is positioned under the first mentioned plate member 37, and is provided with an upper extended portion dl.' The elongated aperture 4t2, is formed in the plate member 40, and is adapted to receive the threaded member 39. The latter described construction being such as will permit the plate member 40, to be adjustably attached to the main member 21, so

In this conas to permit the upper extended portion 4l of the plate member 40, to vary the movement of the back rest properQQ, as may be desired.

Having thus described my invention7 what I claim as new and desire to protect by Letters Patent of the United States is as follows:

In an automobile seat back, a guide member arranged for being pivotally attached at one end to a back member7 having spaced Atherefrom a second guide member7 and a plate member attached on the `free end of the guide member and formed with an arcuate aperture lfor engagement bya screw for holding the guide member in angular positions for rictionally holding an engaging member in a liXed position, the said engaging member being mountedbetween the said guide and the second guide member.

In testimony whereof I have aiixed my signature.
